Over the years I've heard professional travelers like Johnny Jet sing the praises of Scottevest. Johnny has claimed to wear two of them when he travels, one right on top of the other.
You certainly can't fault ceo Scott Jordan for finding ways of getting the word out about his products. There was the recent brouhaha Scottevest got into with Delta over one of their ads, and the round the world challenge Scottevest sent travel writer, Rolf Potts, on.
Scottevests feature up to 26 pockets, are lightweight, windproof and have removable hoods and sleeves. You can keep all your essential items handy: phone, passport, keys, camera, etc. They are even capable of storing an iPad, if you can believe it. They'd probably be great to go shoplifting in an as well. If you're into that sort of thing.
They're pretty pricey, but they might save you a carry-on, as well as time in the security line. If the recently rejected Delta ad is to be believed, they might well be: 'The Most Stylish Way to Beat the System.'
